Wincc: Rest Api

Python is the industry standard for data science and IT automation. Below is a clean, practical script using the requests library to poll data from a WinCC REST API instance.

If your external IT application only needs data for dashboarding (like PowerBI or Grafana), ensure the WinCC API user account is strictly stripped of "write" permissions. Conclusion wincc rest api

The Representational State Transfer (REST) API in WinCC transforms the SCADA platform into an interoperable data server. By utilizing standard HTTP methods, it allows external IT systems to query runtime data without requiring specialized industrial protocols like OPC UA, Modbus, or native Siemens S7 communication. How It Works

An external system (like an MES system or a Python script) sends an HTTP request to the WinCC server's designated port.
